Description

technical field [0001] The invention relates to the field of paint waste gas treatment in the painting industry, in particular to a comprehensive treatment process and device for paint waste gas. Background technique [0002] At present, in many industries such as automobiles, ships, furniture, machinery, electrical equipment, and home appliances, painting and coating have become an indispensable process. Paint raw materials are usually composed of non-volatile components and volatile components. The non-volatile components include film-forming substances and auxiliary film-forming substances, and the volatile components refer to curing agents and diluents. Thinner is a liquid substance with good miscibility with resin added to reduce resin viscosity and improve its process performance. Curing agent can promote rapid drying of paint, increase adhesion and paint surface strength, and improve chemical stability of paint. [0003] The exhaust gas generated by painting is mainl...
